中国目前的经济增长模式虽然带来了二十年稳定而强劲的增长,并使约五亿人脱离了贫穷,但这一增长模式已变得过于依赖信贷和投资,开始显现出收益递减的趋势。如果在推进政府改革行动方面有所延迟,脆弱性将继续增加,向高收入国家趋同过程出现停滞的可能性会增大。另一方面,如果中国实施有关改革,加快全要素生产率增长,使经济不再继续依赖资本积累,则中国经济将能以健康的步伐增长,继续向高收入国家收入水平趋同。中国各省份的证据表明,在提高生产力、保持趋同进程以跻身更加繁荣经济体方面,中国还有空间取得更多进展。

有深度和流动性良好的金融系统,加上有丰富的金融工具可抵御金融冲击,还可以增加一国金融的稳定性。但是金融发展或许存在一个边界,越过此边界进一步发展其收益或将下降。本文通过研究新兴市场发现:一、大部分新兴市场金融进一步发展仍然对经济的增长和稳定有利。二、金融发展对经济增长的促进作用是倒U型的,在越过高点之后金融深化对要素生产率的促进作用将下降。三、如果金融发展过快,快速深化的金融产业可能引发经济和金融动荡。四、提升金融稳定与金融发展之间没有太大冲突,更好的金融监管有助于提升金融稳定,促进金融发展。五、发展金融机构或金融市场不存在通用的顺序,尽管前者对经济的作用在下降而后者在上升。

Here we demonstrate a theory-driven, novel dual-shell coating system of Li_(2)SrSiO_(4) and Al_(2)O_(3), achieved via a facile and scalable sol-gel technique on LiCoO_(2) electrode particles. The optimal thickness of each coating can lead to increased specific capacity(~185 m Ah/g at 0.5 C-rate) at a cut-off potential of 4.5 V, and greater cycling stability at very high C rates(up to 10 C) in half-cells with lithium metal. The mechanism of this superior performance was investigated using a combination of X-ray and electron characterization methods. It shows that the results of this investigation can inform future studies to identify still better dual-shell coating schemes, achieved by such industrially feasible techniques, for application on similar, nickel-rich cathode materials.

Soil survey investigations were carried out in Ferk6 1 as well as Ferk6 2 sugar mills of northern Ivory Coast to determine soil texture and water storage capacity for sprinkler irrigation and tillage management. A 5-year term observation experiment on reduced tillage compared with conventional tillage was also conducted in Ferk6 1 over an irrigated cane crop of 28 ha for yield optimization purpose. Soil sampling was achieved after harvest or prior to re-plantation at five different spots along two transects over 30 cm depth in every farmland which covers about 30-40 ha with 432 m long cane rows as to get an average soil sample of 1.5-2 kg. Soil physical properties like texture and water retention curves were determined locally in the sugar company＇s soil laboratory. It came out that the majority of soils investigated was coarse-textured for about 64% in Ferk6 1 and 85% in Ferk6 2, with a lower to medium water storage capacity （70-89 mm） over 60 cm depth which corresponds to a readily available moisture less than 60 mm. Except for the sugarcane plant crop, no significant difference in cane yields resulting from tillage practices was observed over four consecutive cropping seasons. The yield decline from plant cane to first ratoon was very high under conventional tillage （-16 t/ha） compared with the reduced tillage （＋3 t/ha）. Even higher cane yield was obtained on the second ratoon （89 t/ha） compared with the conventional tillage （83 t/ha）.

In order to study neurotransmitter receptor regulation in the basal ganglia involved in the functional changes underlying levodopa-induced motor complications, quantitative autoradiography was used to observe receptor bindings of dopamine D1 and D2, n-methyl-D-aspartate （nMDA）, amino-3-hydroxy-5-methylisoxazole propionic acid （AMPA） and amino butyric acid （GABA） in the basal ganglia of rats that had unilateral nigrostriatal lesions and had been chronically treated with levodopa until motor complications developed. The rats were randomly assigned to three groups： normal, denervated and treatment-complicated groups. The results showed that response duration to levodopa became progressively shorter and abnormal involuntary movement （AIM） score was progressively increased during the course of levodopa treatment. Chronic treatment augmented D1 receptors more than denervation, and reduced D2 receptors that were also increased by dopamine denervation. Striatal nMDA receptors were substantially up-regulated in the treatment-complicated group. Levodopa treatment did not change receptors of nigral AMPA, pallidal GABA, and subthalamic GABA, which remained the same as that in denervation group. However, chronic treatment reversed the increase of nigral GABA receptors caused by the lesion. It was concluded that a shortening of response duration and AIM mimicked levodopa-induced motor complications of Parkinson＇s patients. These data suggested that up-regulation of dopamine D1 and nMDA receptors in the striatum leads to an imbalance of stimulation through the striatal output pathways, which is associated with levodopa-induced motor complications.

Recent petro-structural investigations on the Faboula gold deposit located in the Bougouni-Kékoro basin, in southern Mali, north-west of the Leo-Man Shield, have provided new data on the nature and spatial organization of the lithostratigraphic units as well as their deformation style. The deposit is covered by a thick lateritic layer and is hosted by a metavolcano-sedimentary sequence of Paleoproterozoic age intersected by intrusive bodies and filled fractures of various shapen>n>sn>n> and typen>n>sn>n>. The lithostratigraphic units consist of metagreywackes, metasiltstones, meta-argillites, slates and schists. Metagreywackes and metasiltstones are generally feldspathic, both may contain biotite and locally amphibole, just as slates may contain andalusite which is locally stretched. Plutonic units most often occur as stocks or as dikes on the drill core, up to 1 m. The metavolcano-sedimentary rocks are schistose and deformed under greenschist facies conditions, n>n>and n>n>locally they reach the epidote-amphibolite facies. The structural study revealed that the deposit is affected by several stages of deformation evolving from a ductile type to a brittle type via a ductile-brittle type. The dominant ductile and brittle-ductile deformations show a combination of isoclinal folding and strike-slip faults. Both the isoclinal folding and the strike-slip faults whose sigmoidal en-echelon tension gashes indicate a dextral movement in the nnE-SSW direction are the result of the same EnE-WSW regional shortening. Consequently, they highlight a transpressive deformation. This deformation noted here D2Fb, could
